Bioenergetic evaluation of miscanthus giant roductivity in the conditions of the western forest- steppe of Ukraine for use as a solid.

Abstract

The regularities of dependence of conditions of growth, development and formation of productivity of a miscanthus giant and increase of productivity at the expense of influence of agrotechnical factors are established in the work: terms of planting and depth of wrapping in the conditions of the western forest-steppe in Podillya. The results of the research are obtained on the peculiarities of the formation of biometric indicators of giant miscanthus depending on the application of a set of technology elements - planting dates, depth of rhizome wrapping. It was found that the increase in land mass of plants in the formation of yield 55.7 t·ha -1 was obtained by planting in the first period (I-II decade of April) to a depth of rhizome wrapping 9 cm. Intensity of land mass increase affected the yield of solid biofuels. During the first planting period with a rhizome wrapping depth of 9 cm, the maximum calculated energy yield of 206.09 GJ·ha -1 was obtained. It is established that the highest yield of bioenergy productivity of perennial miscanthus of the giant variety Autumn Starflower was obtained taking into account soil and climatic factors in the first planting period at rhizome depths of 9 cm, which allows efficient use of soil moisture and temperature during planting.
